The mediating effect of the need for cognition between aesthetic experiences and aesthetic competence in art

Although the role of aesthetics and aesthetic education in everyday life was discussed as early as the ancient philosophers, the psychological mechanisms shaping the aesthetic quotient have hardly been investigated by empirical studies. The aim of this study was to examine the direct relationship between experience and aesthetic competence, and the mediating role of need for cognition. The study involved 201 Polish adults, aged 18 to 76 (M = 26.40; SD = 11.89), 65% of whom were women. The respondents completed anonymous questionnaires on an online platform. The surveys included a metric, the Aesthetic Competence Scale (ACS), the Aesthetic Experience Questionnaire (AEQ) and the Need for Cognition Scale (NCS). A positive correlation coefficient was obtained between all three variables studied, with need for cognition acting as a mediator in the relationship between experience and aesthetic competence. The findings indicate that individuals reporting intense aesthetic experiences have a higher aesthetic competence if this relationship is mediated by a high need for cognitive effort.


Aesthetic competence
Intelligence is undoubtedly one of the most popular areas of interest for psychologists.For example, Legg and Hutter 24, p. 22 analyzed 71 general definitions of intelligence and proposed their own: "Intelligence measures an agent's ability to achieve goals in a wide range of environments." Can this concept be narrowed down to a specific type of aesthetic knowledge and skills?
In psychology, there are various concepts of aesthetic intelligence.A fairly reliable chronological review of the ways in which aesthetic abilities are addressed was made by Dan et al. 2 .Some are complex and include a number of components, such as the Aesthetic Quotient concept developed by Myszkowski and Zenasni 3 .There are also concepts that are almost absent from the psychological literature.For example, Ferrucci 25 , a psychosynthesis therapist, believes that people have a universal capacity for appreciating beauty, termed aesthetic intelligence 26 , which can be nurtured and improved.Therefore, the results of integrating beauty is an idea ("inner transformation") not so distant from the final stages of the art perception described by Pelowski et al. 7 in a systematic way.
Moreover, it can be considered debatable as to how much to emphasize the role of beauty in aesthetic experience and theories centered around beauty when it comes to aesthetic intelligence.Is the concentration on beauty limiting and overlooking other-possibly more relevant-aspects of the aesthetic understanding of art?We acknowledge that beauty is only one of the different components that constitute an aesthetic experience 8 .According to us, it is possible to differentiate between the other aesthetic qualities of an object and its beauty, and we believe that it is possible to have an aesthetic experience with an object that we do not necessarily perceive as beautiful.For example, the paintings of Beksiński (born 1929, died 2005) can hardly be called "beautiful".The ugliness (horror, decay, and visions of destruction) is determined by the content, not the way the elements are composed and the quality of the artist's skills.Their content is a denial of the ancient, Platonic understanding of Beauty, related to Good and Truth, but at the same time, the works of this artist may be recognized and appreciated due to their complexity, ambiguity, and the artist's attention to detail.
As with other intelligence quotient concepts and their domains, the reliable measurement of aesthetic quotient levels poses a considerable challenge.Dan et al. 2, p. 5 write: "People's abilities of artistic perception, appreciation, and creation were chosen as the manifestation of their AQ." They propose that the aesthetic quotient should be measured as a separate assessment of the intensity of aesthetic competence, in various areas of art.The conventional understanding of the word "competence" in Polish 27 , is, "the extent of someone's knowledge, skills and experience, " so it includes not only what is innate but also what is acquired over time.Within the scale developed by Dan et al. 2 , art knowledge, sensitivity (emotional responsiveness to art), understanding (reflection on the work) and the ability to evaluate the quality of a work of art are not viewed as separate components of aesthetic intelligence, but rather as a manifestation of competence in evaluate artworks a particular domain.The overall score is calculated by adding up the results for the different art domains 26 .
Susceptibility to aesthetic experiences (and their intensity) would, therefore, be a component, not a full manifestation of AQ.The authors would like to mention that the degree of convergent validity of the two concepts puzzled us during a broader study aimed at adapting the Aesthetic Experience Questionnaire 28 to Polish cultural conditions.We expected high correlations between aesthetic experiences and aesthetic competence.At the time, we assumed that aesthetic experiences, as overlapping with (included in) aesthetic quotient, should be strongly correlated with ACS, but the correlations were moderate.The findings suggested partial independence of the two constructs.This is consistent with reports indicating that individuals with expert knowledge show a distinct pattern of attenuated emotional and value reactions to the works they see 6 , although, as noted earlier, experts display higher cognitive engagement 4,5 .The authors assume that sensitivity to aesthetic sensations and the accumulation of such experiences are conducive to the development of competence in art, but in order to achieve a high aesthetic quotient and analyze art from angles other than personal preference or sensory pleasure, something else is needed.

Need for cognition
Works of art are sometimes ambiguous, unclear and complex, both in terms of their form and the message conveyed by the artist.The reception of artworks requires reflection and focused engagement.Controlled cognitive processing of an artwork is identified as an important aspect of aesthetic experience 29 .The question is, what makes some people prefer ambiguous art?It is known, for example, that art experts are more likely to enjoy negative or even provocative works 6 .
Presumably, the quality that encourages in-depth analysis of works of art is the need for cognition.Wu et al. 30 , characterize it as an individual's predisposition to engage in and derive pleasure from thinking.Psychologists' interest in this issue has quite a long tradition -a publication that analyzes more than 100 articles presenting the results of research on individual differences in the need for cognition 31,32 has been cited 3549 times to date [Google Scholar, as of 04.04.2023], while Petty et al. 33 noted that more than 1000 articles cited the original article or presented shortened versions of the NCS scale.A high need to explore and engage in intellectual activity is predictive of behaviors related to drives, goals, and allocation of attention and is also correlated with fluid aspects of intelligence and traits, such as openness to experience and emotional stability 34 .Individuals with a high need for cognition enjoy actively thinking about and understanding the world, prefer complex tasks and want to understand causes, and gather as much information as possible before drawing conclusions 35 .
Justification as to why one can feel aesthetic appreciation when viewing an ambiguous image and why cognitive engagement in the reception of art can be pleasurable is provided by neuroaesthetic research.Sarasso et al. 36 report that aesthetic appreciation is correlated with the activation of dopaminergic circuits associated with reward.They explain that aesthetic emotions are a response to behavioral inhibition (physical activity) and promote the enhancement of perceptual processing in the sensory cortices, which are responsible for optimizing learning.The researchers 36, p. 724 suggest that "aesthetic appreciation may represent a hedonic feedback over learning progresses, motivating the individual to inhibit motor routines to seek further knowledge acquisition." Individuals with a high need for cognition may find engagement in viewing works of art more satisfying and rewarding than those with only low levels of this trait.A person who, in addition to being susceptible to aesthetic experience, also tends to enjoy immersing themselves in complex issues, may find it easier to develop high aesthetic competence.

Hypotheses
The positive relationship between aesthetic experiences and the associated competency was observed as far back as antiquity.Plato considered aesthetic education to be one of the key components in the education and upbringing of a free man 37 .Indirectly, data indicates that aesthetic competence is acquired through education and the accumulation of aesthetic experiences.Empirical evidence of a link between frequent exposure to art, acquisition of art knowledge and high aesthetic competence is indicated by the research of Dan et al. 2 .They observed that art students achieved higher levels of AQ than literature students.Indirectly, higher aesthetic competence in those with more experience with art is also demonstrated by a study by Mullenix and Robinet 38 .The participants in the study rated a set of abstract paintings for liking and understanding.Expert knowledge was found to be positively correlated with the level of understanding of the paintings and with faster decision-making (suggesting higher aesthetic competence) but not with liking.Accordingly, this study assumed that: H1 Aesthetic experience is positively related to aesthetic competence.
According to D'Olimpio 9 , aesthetic experiences have a phenomenological quality that includes being absorbed, focused, and open.In order for aesthetic experience to be enriching, one needs to be interested in exploring a new object and to show curiosity, coupled with excitement and anticipation of what can happen by engaging with and perceiving the object.The desire for exploration associated with exposure to art, which the researcher describes from a pedagogical perspective, seems consistent with the psychological understanding of the need for cognition.
Data suggests that a high need for cognition is correlated with three of the five dimensions of flow: focused concentration, sense of control, and curiosity 39 .If flow is recognized as a potential component of aesthetic experience 8 , then declaring a stronger aesthetic experience is more likely to be positively associated with a higher need for cognition.In research on the construction of the Aesthetic Experience Questionnaire, Wanzer and her team 8 verified the correlations between aesthetic experiences and measures of openness to experience, Vol:.( 1234567890 www.nature.com/scientificreports/inspiration, curiosity, and exploration.Further, the research on the Polish adaptation of this scale revealed that "[t]he inclination for analytical observation of reality may encourage greater engagement in contemplation of art" 28, p. 04 , as aesthetic experience is correlated with need for cognition.Therefore, the following hypothesis was formed: H2 Aesthetic experience is positively related to need for cognition. Kowalik 40 writes from the perspective of a practicing psychologist and a scientist that both creating and receiving art are specific ways of learning about reality.He describes at least three types of cognitive void (metaphysical, epistemic and existential), which people try to limit, to fill selectively or globally, with various types of art.In general, about all types of cognitive void experienced by people, he metaphorically wrote that it is a "blank spot" in the space already known, which needs to be filled.And so, successively, the metaphysical void is, "the feeling of the non-existence of something that we would like to exist" 40, p. 399 and the psychological function of the metaphysical void is to organize the ontological space being explored and to enable it to be enriched with fictitious elements.An epistemic void is a "lack of knowledge about something that we suppose may exist (or indeed does exist), but for some reason is inaccessible to our cognition" 40, p. 399 .Filling the epistemic space is mainly the responsibility of scientists and individuals who feel individual deficiencies in epistemic knowledge and try to fill this kind of void by referring to individual experience.The third type of void is an existential void, which differs from the previous ones in that it concerns introspective awareness, the feeling of not knowing oneself (lack of knowledge about one's inner life, surprise with one's own behaviors, differences between the self and others, etc.).Having a strong need for cognition promotes the integration of previous art knowledge and experience and prompts the viewer to reduce feelings of uncertainty.Since intellectual engagement with art is self-rewarding 36 , presumably the repetitive nature of this process will translate into increased aesthetic competence.The following assumption was therefore made: H3 A high need for cognition is positively related to aesthetic competence.
With reference to the data cited in the literature review, it was assumed that individuals reporting higher levels of aesthetic experience would exhibit a higher aesthetic quotient if they had a high need to engage in intellectually challenging tasks.In addition, putting need for cognition in the role of mediator between aesthetic experience and aesthetic quotient would be in line with data on other thematic studies in which the NCF acted as a mediator [41][42][43] or moderator [44][45][46] .For that reason, the expectation was as follows: H4 Need for cognition plays a mediating role in the relationship between aesthetic experience and aesthetic competence.

Tools Aesthetic Competence Scale
The Aesthetic Competence Scale (ACS), created by Dan et al. 2 , is used to measure the aesthetic quotient in relation to four selected art areas.It refers to the extent to which the recipient can assess the quality of artworks but it does not measure proficiency in artistic skills.The Polish version of the tool was used in this study 26 .The scale consists of 20 statements, with five each being part of the competence factor in music, visual arts, literature, and film.The respondents expressed their opinions using a five-point Likert scale (1 = "strongly disagree, " 5 = "strongly agree").The sum of the scores from all subscales indicates the overall level of aesthetic competence in the arts.The higher the overall score, the greater the aesthetic competence of the respondent.In the present study, the individual dimensions, as well as the overall score, had high reliability coefficients: music (α = 0.90), visual arts (α = 0.89), literature (α = 0.91), film (α = 0.92) and the overall aesthetic competence score (α = 0.96).

Need for Cognition Scale
The Need for Cognition Scale (NCS) is a one-dimensional tool to assess the propensity to engage in and enjoy cognitively demanding tasks.The original version of the tool, created by Cacioppo and Petty 31,32 , was adapted to Polish conditions by Matusz et al. 47 .The questionnaire consists of 36 statements rated by respondents on a fivepoint Likert scale (from 1-"strongly disagree" to 5-"strongly agree").The points obtained by the respondent are summed up to obtain the overall score.A high overall score indicates a high need for cognitive engagement.In the present study, Cronbach's alpha coefficient was α = 0.86.

Aesthetic Experience Questionnaire
The Aesthetic Experience Questionnaire (AEQ), created by Wanzer et al. 8 , assesses the intensity of experiences associated with exposure to art.As intended by the authors, the scale applies primarily to the visual arts (e.g., painting, drawing, sculpture, and printmaking), but can also be applied to other areas of art.The study used the Polish version of the AEQ 28 .Like the original, the Polish version contains 22 statements grouped into six aspects of aesthetic experience: the emotional, cultural, perceptual and understanding dimensions, conditions conducive to flow, and experience of the flow state.Survey participants check the degree to which they agree with each statement they read on a 7-point Likert scale (where 1 means "strongly disagree" and 7 "strongly agree").The points are added up within each of the subscales.An overall score is also available.In this study, the reliability coefficient proved satisfactory for all dimensions of the questionnaire: emotional (α = 0.91), cultural www.nature.com/scientificreports/(α = 0.86), perceptual (α = 0.88), understanding (α = 0.86), conditions conducive to flow (α = 0.88), experience of flow (α = 0.91), as well as for the overall score (α = 0.96).

Study group and procedure
The study involved 201 adult Poles, with 65% of the respondents being women.The participants' ages ranged from 18 to 76 (M = 26.40;SD = 11.89).The participants were asked about their level of education.The largest group was currently studying (48%), followed by individuals with higher education (33%), with significantly fewer respondents declaring that they had obtained secondary education (9%), vocational technical education (6%) or primary education (3%).The fewest respondents reported vocational education (1%).
A number of studies have focused on the differences between experts and non-experts (novices or those with particularly low aesthetic scores).We wanted to understand the general direction of the relationship between aesthetic experience and aesthetic quotient, so we decided not to divide the study sample by expertise.We tried to exclude individuals who were completely uninvolved or disinterested in art, as well as those with a very high level of expertise (e.g.several years of work in the arts) from participating in the study and reached out mainly to those declaring average interest and/or amateur involvement in the arts.
Non-random sampling (accidental and snowball sampling) was used.The respondents were made aware of the purpose of the study, its structure, potential duration, the possibility of discontinuing participation at any time and about the anonymity and confidentiality of individual results.All participants provided informed, written consent.The study was based on an online, asynchronous, one-time questionnaire.The research process took place under Approval No 6/2022 of the Research Ethics Committee of the Institute of Psychology at the University of Szczecin.All methods were carried out in accordance with the Declaration of Helsinki.

Statistical analysis
Analysis of the data obtained was carried out using IBM SPSS Statistics 23.0 and the PROCESS macro for SPSS (version 3.2) 48 .The data distribution was examined by means of the Shapiro-Wilk test 49,50 .Since such normal distribution values were not obtained in our study, a Spearman's Rho correlation was performed to verify the association between aesthetic experience, need for cognition, and aesthetic competence.
A linear regression model was used to (1) detect the degree of multicollinearity, (2) locate prospective outliers and (3) account for potential confounders, and to scan whether they were impacting the existent relationship between the independent (aesthetic experience) and dependent (aesthetic competence) variables.First, because we counted that the explanatory variables (aesthetic experience and need for cognition) could share considerable variance, we scrutinized whether there would be a multicollinearity problem.To diagnose collinearity, we used overall measures (the tolerance statistics and the variance inflation factors, VIF) 51 .Tolerance lower than 0.1 to 0.2 and VIF larger than 5 to 10 52 were assumed as indicators of a serious multicollinearity problem.Next, we computed Mahalanobis' distance (p < 0.001) and Cook's distance (greater than 1) to screen for the presence of multivariate outliers 53 .Finally, the respondents'gender, age and education were inserted to control for their potential impact on the relationship between the aesthetic experience and aesthetic competence.Indeed, there is some empirical evidence, although very limited, that sex has an effect when it comes to art.Some subtle differences between women and men can be noticed with respect to aesthetics 54 .Age has also been found important for the development of aesthetic experience and judgment 55 .Moreover, aesthetic experience has been considered as a part of the social world 56 and cultural experience 56,57 , thus being possibly associated with the level of education.All three potential confounders (gender, age, and education) were entered at Step 1.All predictors of aesthetic competence were entered at Step 2. Information about multicollinearity, outliers, and confounding factors is provided in the Supplementary materials.

Descriptive statistics and correlations
Descriptive statistics for the mean, standard deviation, values of the Shapiro-Wilk test, and correlations for each variable are shown in Table 1.Since the Shapiro-Wilk tests for normality showed that only the NCS presented a non-significant p value, Spearman's Rho correlations were calculated for each variable considered in the study (aesthetic experience, aesthetic competence, need for cognition).

Mediating effect of need for cognition
In order to verify the hypothesis that need for cognition (H4) plays a mediating role in the relationship between aesthetic experience and aesthetic competence, Model 4, a single-mediator mediation model, was chosen (Fig. 1).www.nature.com/scientificreports/ The results of the analysis indicate that aesthetic experience is an explanatory variable for need for cognition.This means that a high intensity of aesthetic experience is predictive of a high need for cognition (path a: β = 0.0057; p < 0.001).In addition, need for cognition was found to be predictive of the level of aesthetic competence (path b: β = 8.7974; p < 0.001).
In the next step, the occurrence of mediation was verified using the 5,000 bootstrap samples method, assuming a 95% confidence interval without zero.A statistically significant indirect effect (0.0504) with B(SE) = 0.0137 was observed for the impact of aesthetic experience on the level of aesthetic competence, with need for cognition as a mediator (95% CI: 0.0262; 0.0792).The results indicate that β = 0.2057 at p < 0.001 (path c) decreases to β = 0.1553 at p < 0.001 (path c′), confirming the mediating role of the need for cognitive stimulation (H4).

Discussion
The established hypotheses were confirmed by statistical analyses.The results obtained are consistent with reports by Dan et al. 2 and Myszkowski and Zenasni 3 stating that interaction with art and emotional and cognitive engagement in its reception promotes the development of aesthetic competence in appraising artworks.The results contribute new knowledge to the existing body of data in the literature.Arguably, this is the first mediated study to further clarify the role of the need for cognition in the formation of aesthetic competence.The need for cognition provides an opportunity to explore the impact of the arts on our senses and thinking and helps ensure that aesthetic experiences are collected and analyzed in a purposeful way, supporting the development of aesthetic competence.
From an evolutionary perspective, the ability to receive and create art can hardly be seen as adaptive for the species.Luty, citing Dutton 58, p. 31 , argues that art is a by-product of one or more other cognitive abilities.On the other hand, this "side effect" can improve an individual's adaptability in everyday life.Although the arts seemingly do not have the power to directly improve people's lives and, perhaps for this reason, remain a marginalized area of general psychological knowledge 38 , the information and new perspectives gained from viewing, listening to or practicing them can be used to better cope with the challenges of everyday life.It is known, for example, that creative artistic activity facilitates coping with emotions through the acquisition of new insights, self-development or distancing oneself and avoiding difficulties 59 , while listening to music not only regulates emotions, such as excitement but also serves a communal, bonding function 60 .By experiencing art and increasing aesthetic competence through the need for cognition, one builds sensitivity to details, a broader context and an understanding of cultural phenomena, and learns to be open to the non-obvious and ambiguous.
Finally, it should be added that it is important that this paper popularizes two relatively new psychological tools (ACS and AEQ) that have only been validated for Polish cultural conditions in recent months, so it simultaneously validates the psychometric properties of these tools and encourages other researchers to use them in their projects.
In addition, it is noteworthy that age proved to be a confounding variable, which suggests that aesthetic competence decreases with age.Younger people (high school graduates) may have higher competences in art, because knowledge about art and culture has been acquired during obligatory education or gained thanks to the Internet and its ease of access.In people in middle adulthood, engagement with arts (unless someone works or has a hobby in this field) is probably not a priority in this period of life, considering that middle adults' developmental tasks require a lot of time, energy, and resources, which do not leave space for art.

Limitations
As with any quantitative, online study, despite the care taken to ensure that the survey was a one-time event, that consent was obtained and that access to the link was terminated upon completion of the survey, there were limitations inherent in this form of data collection 61 .Doubts may be raised about the sample.Eighty percent of the participants had higher education or were studying at university and the mean age of the respondents was approx.26.In order to relate the results to the general population, it is advisable to conduct the survey among a group of people with different educational backgrounds and a higher modal value for age, and to compare the results based on the expertise in each art area.
A limitation of the authors' study is the fact that art-related scales were used.This means that we cannot extend the conclusions from our research to aesthetic competences in general, i.e. non-artistic ones.In fact, any stimulus can be perceived as aesthetic, and aesthetics and art are two separate theoretical constructs.It is possible https://doi.org/10.1038/s41598-024-53957-6
